Securing electronic document exchange after signing

The adoption of electronic document management (EDM) has become standard for many companies seeking to optimize business processes and enhance efficiency. However, the transition to digital documents raises several questions regarding their security and legal validity after signing. Understanding these aspects is crucial for ensuring the reliability and trust in EDM.

Softline IT specialists recommend not only implementing EDM but also paying special attention to the comprehensive protection of electronic documents throughout their lifecycle, including the period after signing. This will minimize risks and ensure compliance with legal requirements.

What is electronic document management (EDM)?

Electronic document management (EDM) is a system for exchanging documents in electronic form, signed with an electronic signature (ES), which holds the same legal force as paper documents with handwritten signatures. It covers the entire document workflow: creation, approval, signing, storage, and exchange.

Why it matters for business

Ignoring the security of electronic documents after signing can lead to serious consequences for a company.

• Risk: Unauthorized access or modification of a signed document.
• Consequence: Loss of legal validity of the document, compromise of confidential information.
• Business impact: Financial losses, reputational damage, lawsuits, fines.

• Risk: Loss of electronic documents due to technical failures or cyberattacks.
• Consequence: Inability to confirm agreements, absence of primary documents for audits.
• Business impact: Disruption of business operations, tax issues, data loss.

• Risk: Non-recognition of the electronic signature or its compromise.
• Consequence: Doubts about document authenticity, refusal of counterparties to fulfill obligations.
• Business impact: Delays in transactions, additional costs to restore trust, loss of clients.

How it works in practice: the journey of a signed document

After an electronic document is signed with a qualified electronic signature (QES), it undergoes several stages to ensure its integrity and legal validity.

1. Electronic signature generation

When a user signs a document, the EDM software generates a unique cryptographic hash of the document. This hash, along with the signer’s data (their private key), is encrypted and appended to the document as an electronic signature. This signature contains information about who signed the document, when, and with which key. Consequently, any subsequent changes to the document will be immediately detected.

2. Document transmission

The signed document, often in PDF or XML format, along with the electronic signature (which can be embedded in the document or stored as a separate .p7s file), is transmitted to the counterparty or storage system. Transmission occurs over secure communication channels (e.g., HTTPS), preventing data interception and modification during transit.

3. Authenticity and integrity verification

The recipient of the document can verify its authenticity and integrity. This is done by decrypting the electronic signature using the signer’s public key and comparing the obtained hash with the hash generated from the received document. If the hashes match, the document has not been altered since signing. The validity of the ES certificate is also checked with the relevant certification authority (CA) to ensure the signature is valid and has not been revoked.

4. Archiving and long-term storage

After successful verification, the document is moved to an electronic archive. EDM systems provide long-term document storage, often using multi-tiered backup systems, geographically distributed storage, and encryption. This ensures document availability for the entire required period (e.g., 3, 5, 10 years or more, depending on the document type and legal requirements) and protection against data loss.

5. Legal force and evidentiary value

An electronic document signed with a QES has full legal force and can be used as evidence in court. This is ensured by the Law of Ukraine “On Electronic Trust Services,” which equates QES with a handwritten signature. An additional guarantee is the use of timestamps, which confirm the fact of document signing at a specific moment in time, making date manipulation impossible.

Practical case: ensuring business continuity

A mid-sized electronics distribution business faced a challenge. Due to increased sales volumes and an expanding partner network, the number of paper contracts, acts, and invoices grew significantly. This led to processing delays, risks of document loss, and high costs for logistics and storage. The company decided to implement a comprehensive EDM system.

Softline IT developed a solution based on Microsoft SharePoint for internal document management and integrated it with a popular EDM provider for external exchange with partners. A centralized document repository was implemented with multi-tiered access based on user roles. Each signed document was automatically encrypted and stored in multiple copies on geographically distributed VMware servers, as well as in Azure cloud storage. For added security, a Cisco cybersecurity monitoring system was configured to track any attempts at unauthorized access or modification.

Six months after implementation, an incident occurred: one of the company’s remote servers failed due to a hardware malfunction. Thanks to Softline IT’s solutions, not a single document was lost. All signed contracts, acts, and invoices were accessible from backup copies, and their legal validity was confirmed by electronic signatures and timestamps. The company was able to quickly resume operations, avoid penalties, and maintain partner trust, demonstrating a high level of reliability in its processes.

Common mistakes

• Mistake: Using insecure channels for document exchange.
• Consequence: Risk of data interception and compromise.

• Mistake: Lack of backup for electronic documents.
• Consequence: Irreversible loss of important information in case of failure.

• Mistake: Neglecting regular verification of electronic signature validity.
• Consequence: A document may lose legal force if its certificate has been revoked.

How to implement secure EDM

1. Choosing a reliable EDM provider and system integrator

Select an EDM provider that guarantees a high level of data protection, uses qualified electronic signatures, and complies with all legal requirements. Engage an experienced system integrator, like Softline IT, for comprehensive implementation and integration of the EDM system with your infrastructure (corporate networks, servers, clouds).

2. Implementing comprehensive cybersecurity solutions

Ensure the protection of your IT infrastructure against cyberattacks. Utilize cybersecurity solutions from leading manufacturers (e.g., Cisco), intrusion detection systems, antivirus protection, and firewalls. This will create a robust barrier to protect electronic documents.

3. Regular backup and archiving

Configure automatic backup of all electronic documents to cloud storage (e.g., Microsoft Azure) or remote servers. Develop a long-term storage policy that complies with legal norms and internal company requirements, using solutions from VMware or Oracle.

FAQ

What is the difference between an electronic signature and a qualified electronic signature (QES)?

A QES has the highest level of trust and legal force, equating to a handwritten signature. A standard electronic signature (ES) can be used for identification but does not always carry the same legal weight as a QES.

Do I need to keep paper copies of documents signed via EDM?

Ukrainian legislation allows for not keeping paper copies of documents signed with QES, as the electronic original has full legal force. However, some internal policies or partner requirements may stipulate duplication.

How long should electronic documents be stored?

The storage periods for electronic documents are regulated by Ukrainian law and depend on the document type. For example, accounting documents may require 3 years of storage, and personnel documents up to 75 years. It is important to configure the EDM system according to these requirements.

What to do if an electronic signature is compromised?

In case of compromise of a QES private key, immediately contact an accredited certification authority (ACA) to block and re-issue it. EDM systems should have mechanisms to track certificate status.
